Global GDP growth is expected to slow to 3.2% in 2011 and stay there in 2012. India’s GDP is expected to be $ 30-trillion by 2030. It has been projected that there will be ten-fold growth in the global economy, from US$32 trillion at its onset in 2000 to US$62 trillion today and US$308 trillion in nominal terms by 2030.

The first industrial revolution spanned 1870 to 1913 and marked the emergence of the U.S. as the world's biggest economy.

Japan and the Asian tigers—Hong Kong, Singapore, South Korea, and Taiwan—grew from the second economic surge, which began after World War II.

Standard Chartered Bank says the current supercycle will push the world economy from $62 trillion in 2010 to a projected $308 trillion by 2030, with emerging economies accounting for 68 percent of that growth.
